Description
The Harmonic Barrel Tuner allows you to fine-tune your rifle's barrel/liner to the ammunition you use. With every shot, small fluctuations occur in your barrel/liner, and now you can adjust these fluctuations. The accuracy of your airgun can be greatly improved by adjusting the frequency of these oscillations.
If you want to experiment with the accuracy of your airgun, here is your chance. Note that there is no definite rule of thumb for the perfect setting and you will need to do a lot of testing to find out which settings work best for your airgun/ammunition.
